FOLDING BED.

SPECIFICATION forming part of Letters Patent No. 332,460, dated May 8, 1888. Application filed J..nuary 24, 188'!A `Serial No. 225,238. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. Cocina citizen of the United States, residing at Chicago, 1n the county of Cook and State of Illinois,

5 have invented a new and useful Improvement 1n Folding Beds, of which the following is a specication.

My invention relates to improvements in the mannerofbalancinguprightfoldingbeds which Io are opened and closed by the canting principle.

The objects of the improvements are, first, to avoid the use of springs entirely, as they are dangerous on account of their liability to pull the upright bed over and also to break; second, to furnish a counterbalancing principle for folding beds which will not require as much Weight as beds of this class in present use, and which are Weighted so heavily that it makes it zo impossible for alady or servant to move them, as they would often desire; third, to simplify and cheapen the beds, in order that they may come within the means of the poorer class. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a back view ofthe bed when open, with parts broken away, showing my invention; Fig. 2, a side sectional View of the open bed, showing position of the pivoted front rail,

3o O; Fig. 3, an end View of the flanged socket b.

Similar letters refer to similar parts.

In Fig. 2,0 represents the front and adjustable part of the bed; K, the upright or frame;

Q, the back or sliding headboard, all as usually constructed by others. I hingeand pivot these parts together by any ot' the known deA vices, making no claim thereto.

My invention is principally confined to the lever composing the arm B and pan A, pro- 4o vided with the two sheaves C C at one end and the weights c at the other end, operating in combination with other known parts. Across the top of the head-board or sliding back is the cleat g', through which (edgewise) the bolt is placed, the lower end of which is formed into a hook, the upper end provided with the thread and nut i'. Attached to this bolt and extending to the bottom of the frame K is the cable E, each end of which is provided with 5o the eyes e, one of which is hooked to the bolt i'. A portion of the other eye is let through the bottom of the frame and held by the key f, which passes through the lower end of the eye and under the bottom ofthe frame. (Shown in Fig. 2.) By the use of these eyes and bolts the tendency to wear the cable is avoided, and by the use of the thread and nut i the proper tension can be had on the cable. On the back of the frame, about two-thirds of the distance from the top to the bottom, is placed the brace and support H. Between this brace and the cable E is placed the pivoted end B of the len ver, which is hinged to the brace near the oenter by means of the anged socket b and the arbor b, the arbor projecting from the face of thelever through the socket. On the opposite or back side of the lever the two eccentrical`acting sheaves G C are placed,and pivoted as close to the pivoted center of thelevler as the 'cable which passes between them or the edges of the sheaves will permit. The sheaves are placed in such a position onthe lever that when the outer and weighted end of the lever is elevated to the highest point, as in Fig. l, the purchase upon the cablewhich passes between thesheaves is in close proximity to the fulcrum b of the le- Ver, the cable running to the right of the upper sheave and to the left of the lower sheave. This is the position ofthe lever where the greatest purchase is had, ,and a point Where the greatest purchase is required, owing to the fact that while the lever is in this position the pivoted frame O, (shown as a part of the bed proper, and which is to be tilted upward,) slat its heaviest position, being parallel with the floor.

To operate the bed it will readily be understood that as the frame O is pivoted to the sides of theframe K, (shown at NV in Fig. 2,) and the sliding headboard Q, hinged to the frame O by means ofthe bars XX, one end of 9o which is hinged to the bottom of the headboard, as shown at the other end hinged to the frame O, (shown at x2) the operator has only to lift at the front end of the bed-frame,

Awhen the weighted end of the lever will swing in the direction ofthe arrow, the sheaves will revolve in opposite directions, the cable and headboard will draw down from the top, the lower sheave will take the position of the upper one, andv by the connections described the IOO front of the bed will be properly counterbalanced and easily closed or opened.

In order to adjust the weights for balancing the bed at the two extreme points up or down, and Where beds are constructed of light or heavy material, I use one or more blocks of wood formed in shape and size as the iron Weights, by a proper adjustment of Which an accurate adjustmentishadin balancing thebed shownin Fig. l-a representing Athe wood, ce the iron.' The weights are held in position by the setsereW t. The cleats d d are attachedto the sliding back to prevent the lever from swing# ing too far in opening the bed.

If desired, in order to getstrength and durability, chains can be used instead of the cable.

What I claim as new, and. desire to secure by Letters Patent as my invention, is

l. The combination, in folding beds of the class herein shown, having the sliding back or headboard Q, of the chain or cable E, one end of which is permanently attached at the bottom of the frame K, the other end attached to the top of said head-board, the lever B, pivoted to the support H and provided with th pan A for holding Weights a, and the purchasebearing sheaves O O, pivoted to said lever and arranged to revolve against said cable, all sub stantially as set forth. l

2. In a folding bed, the combination of the stationary section provided with the supportpiece II, the weighted lever B, pivoted to said supportand provided with the sheaves O G on the short arm thereof, the folding section of the bed pivotal] y attached to the stationary section having the sliding headboard, and the cable E, running between the sheaves O C and having one end attached to the bottom of the stationary Case and the other end to the sliding head-board, substantially as described.
